locked Re: General Availability (GA) Release of WSJT-X version 2.5.0 #GeneralGroupInfo

Hi Bill,

excessively optimistic signal reports are often due to restricted receiver bandwidth. The FT8 decoder relies on a reasonably flat receiver bandwidth across the displayed waterfall, and at least 2500 Hz wide. Narrower input data bandwidth will cause underestimation of the noise level.

I don’t feel so bad…. I have been giving +10 to +20 but receiving -15 to -20 dB.

I noticed a similar thing on the evening of 10/02 on 10m FT8.  There was a good opening from W1 land to LU and PY land, and I was getting -15 to +05 and I was giving out +20 and most around +10.  Interesting.

Same here, v2.5.0 downloaded and installed perfectly. One thing I do notice is that there seem to be a much wider range of received signal strengths, with quite a few lower than they might have been with previous releases. Maybe WSJT-X, maybe recent Windows updates altering the CODEC settings. No problems operating, just rather disconcerting when I sent -01 to an N4 earlier and got +30 back!
